LIQUID-SPRAYER.

Specification of Letters Patent.

Patented sept. 24, 1912.

Application filed December 1, 1910. Serial No. 595,110.

To all whom; it mag concern Be. it known that I, WILLIAM B. Coun- TER, a citizen of the United States, residing at Seattle; in t-he'county of King and State 5 of Washington, have invented certain new and useful Improvements in Liquid-Sprayers; and I ,do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spraying devices and has for an object to provide means attachable to hose of common and ordinary 15 usage and by employing which germicide or other medicament may be sprayed upon trees shrubs or the like. 4

A further object of the invention is to provide a reservoir adapted for holding a fluid with improved means for commingling such fluid with Water which is employed for producing the spray.

A further object of the invention is to provide an improved nozzle adapted for 25 producing a spray from water employed and havin improved means for commingling a medicating fluid with said water.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter morefully described and claimed.

In the drawings: Figure 1, is a view of the device showing the reservoir in side elevation with certain parts broken away and showing the nozzle in section. Fig. 2, is a top plan view of the air valve. Fig. 3, is a view in side elevation of the cock employed to control the flow offluid from the reservoir to the nozzle.

Like characters of reference designate corresponding parts throughout the several views.

A reservoir is employed having a nipple 11 adapted for the introduction of fluid which nipple is closed in any approved manner as by the use of the screw cap 12. An opening 13 is also provided in some approved part of the reservoir with a valve 14 seated therein held normally yieldingly closed by a spring 15 which permits-air to enter the reservoir as the fluid contents is discharged.

Preferably the opening 13 is elliptical in 55 form and the valve 14 also elliptical in form as indicated particularly at Fig. 2

with a shank 16 squared to engage the spider 17 to revent such valve from turnafter which it is turned to normal position and the spider 17 set, spring 15 put into place and a tension nut 18 employed to exert .therequired tension upon the valve 14.

Communicating with the reservoir 10' isa valve or cook 19 having a turning plug 20 located therein controlled by a winged head 21 for rotating such turning plu 20. The turning plug 20 is providedwith an indicating mark 22 while thefbody of the valve is provided with a graduated scale 23 by comparison of which it can be determined from inspection to what extent the turning plug 20 is' turned to produce registration through the valve. In other words it can be determined from inspection how great an orifice is provided for the passage of fluid from the reservoir 10 through the cock. At its lower end the cook 19 is fitted with a T-coupling 24 into one end of which a hose coupling 25' may be inserted connected with the hose shown conventionally at 26 while into the other end of such T-coupling a pipe section 27 is inserted having a reducer cap 28 upon its extremity serving as a nozzle. In axial alinement with the nozzle 28 a cone 29 is mounted carried upon a rod 30 slidable through spaced ears 31, such rod 30 being provided with screw threads and controlled y 'a nut 32 disposed between the ears 31. The end of the nozzle is also preferably retained in spaced relation with the reservoir by a strut 33 rigidly connected both with the reservoir and the nozzle 28. The lower end of the cook 19 is also fitted with an L-coupling 34 to which is connected a pipe 35 ex tending within and concentric with the pipe 27 with a reduced extremity 36 disposed concentrically within the nozzle 28 and in aline-. ment with the apex of the cone 29.

In operation the reservoir 10 is filled with germicide or anyfluid which it is desired to spray upon trees, plants or the like in diluted form and the device connected wit-h a water hose indicated conventionally at 26 connected with any sort of water supply under pressure. The turning plug 20 is then turned until a suflicient opening is indicated by the scale 22 and 23 which indicates the quantity of fluid flowing from the reservoir 10 through the pipe 35 and associated with the water in the nozzle 28 and the comone end of the T-coupling, an elbow connected with the stop cock disposed Within the T-c'oupling, a discharge tube connected with the elbow and disposed axially Within the water discharge pipe and ez tending beyond the end thereof. and termlnatlng 1n a tapered reduced extremity, a discharge nozzle connected with the discharge pipe being of, reduced diameter and carrying capacity and embracing but extendlng beyond the end of the tube, and means located at the end of the discharge nozzle for dividing the discharge into a spray.

In testimony whereof I atfix my signature in presence of two Witnesses.
